how likely is it that a human programmer will use a bad formatting
character that's not in the ASCII range?

-1 on removing it -- people shouldn't have to learn the octal ASCII
table just to be able to fix trivial typos.

+1 on mapping the character back to a string in the same was as
"repr" -- that is, print ASCII characters as is, map anything else to
an octal escape.

+0 on leaving it as it is, or mapping non-printables to "?".
